Specification of Letters Patent.

Patented Feb. 25, 1919,

Application led June 25, 1918. i Serial No. 241,893.

To all whom it may concern Be it known that l, GEORGE Y. YAsUMUnA, a subject of the ilnperor oi' Japan, residing at Seattle, in the county of King and State of lVashington, have `invented a certain new and useful improvement in lee Cream-Conc Machines, of which the following is a specification.

My invention relates to improvements in machines for baking cone shaped pastry receptacles of the form commonly termed ice cream cones and the object of myv invention is to provide va machine that is simple in iits plan of construction, easy to operate 'andr economical in its consumption oi' fuel.

lFurther objects reside in the details of construction hereinafter more fully described and claimed.

1 accomplish these objects by devices illustrated in`the accompanying drawings, wherein- Figure 1 is a plan view of Aa machine constructed in accordance with my invention, the arm for supporting the die members in uplift/ed position being 'broken away;

Fig. 2 is a View in sectional elevation substantially on broken line 2, 2 of Fig. 1;

Fig. 3 isy a plan view of one of the molds as it 4may appear when in a partly open position; and

Fig. Li, is a view in elevation illustrating the devices or clampingithe mold and die sections together. i

Referring' to the drawings throughout' which like reference numerals indicate like parts, the numeral 6 designates a base which supports a vertical post formed of three tubular sections 7,8 and 9.

The section 7 is secured tothe base 6 by a pipe fitting 10 that also serves as a means of communication between the interior passageway of the post and itwo pipes 11 and 12 respectively, as shown in Fig. 1, one of which is an air inlet and the other of which is a gas inlet pipe.

secured flanges 17 that are formed integral with radially proj ecting arms 18.

The outer ends of the arms 18 are each provided on each side with four semi-conical. shaped recesses 20 that coact with other parts hereinafter described to form coneshaped molds.

as at 24 for the reception ofthe ends of the die-plates 25 that are mountedv for oscillating movement on pivots 26. i l

The die-plates 25 are provided fwijth a plurality of. conical dies 27 thatV are suitably arranged to lit within the conical molds formed in the `sections 420 and'23 inV the mold arms 18 and 21, the dies 27 being suficiently smaller than the molds so thait a relatively thin space is left between the .walls of the dies and the walls of the molds when the dies are inserted therein, which space may be filled with batter that may be baked to form a cone-shaped pastry receptacle. The outer ends ofthe members 21 are each provided `with outwardly 'projecting rods or bars 28 upon one of which is pivotally mounted a hook mem- .ber 29 that may be hooked over the opposite rod 28 as more clearly shown inFig. 4, to secure the mold sections 22 in engagement with the arm 18.

The outer end ot' the die-plate 25 is also provided with an outwardly directed rod or bar 8O that is adapted to be engaged by a hook 31 which is pivotally mounted on one of the rods 28' and serves to hold theA die section securely in contact with the mold sections, the outer end of the rod is bent at right angles -to the remaining portion thereof and is adapted to be engaged' by a` hook 32 on the end of an arm 33 that l is pivotally mounted between lugs 34 on a cap 35 on the top end of the post section 9.

The arm 33 is provided adjacent the lugs 34 with a leg 36 that is adapted to Strike against the top of the cap 85 to hold the arm 3S in an upwardly inclined position.

The two rods 28 a-nd the rod 30 are constructed of springy material, so that when they are secured by the hooks 29 and 31 the several mold and die sections will be held securely in contact with each other.

The machine herein disclosed has five radially projecting die and mold sections but it will be understood that either a greater or less number of similar mold section may be successfully embodied in a practical machine.

The five mold sections are substantially identical in construction so that a descrip- Ition of one section will apply equally well 4 to all of the others.

The coupling member 14 is provided with four radially directed fuel pipes 37, 3S, 39 and that are arranged to project outwardly above four of the die and mold menibers, the fifth fuel pipe being omitted to leave a space where one of the molds may be opened for the purpose of inserting batter and removing the baked cones.

The pipes 37, 38, 39 and 10 are each connectedwith Y fittings which in turn are each connected with two burner pipes 42 that are perforated as at #L3 on their bottom sides so that they will direct jets of gas downwardly on tothe top of the die sections.

The coupling member 13 is provided with four radially directed pipes 41- that correspond in relative position to the pipes 3T, 3S, 39 and t() and are connected by Y fittings 45 with burner pipes 46 that are perforated in their top sides as at 4:7 so that they will direct jets of gas upwardly around the mold sections.

If desired an arm 50 may be fixedly secured to one of the upright post sections above the plane of rotation of the molds and may be provided on its outer end with a shelf 51 that may serve as a support for a vessel inwhich batter-for filling the molds may be placed.

rfhe operation of my invention may be described. as follows: Gas and air in the correct proportions may be admit-ted through the pipes ll'and 12 into the passageway within the upright post and permitted to pass outwardly through the coupling mem# bers 18 and'lal to the burner pipes 4:2 and 46 from whence it issues through the perforations 43 and 17 and may be ignited to produce a flame thatsubstantially envelops the die and mold sections.

As soon as the molds have become. heated one of the heated molds may be moved into the filling position, the die section may be raised as shown in Fig. 2. The molds and die section are then greased to keep the cooked cones from sticking to said molds and die sections` then a small amount of batter may be placedl in each conical recess in the moldsthe die section may be lowered t0 cause the dies 27 to squeeze the batter linto'the narrow space between the walls of the dies 27 and the walls of the mold recesses 20 and 23. The molds may then be rotated on the upright post through one fifth of one complete revolution to bring the filled mold between the first set of burner pipes and to bring the neXt mold into the filling position which next mold may be filled in the same manner as the preceding one. This operation may be repeated unt-il the mold that was first filled has been moved through one complete revolution and allowed to bake the batter therein for a short time between each of the four sets of burner pipes So that when this mold again reaches the filling position the die is raised as shown in Fig, 2. A fin of batter spreads out on top of arm 18 and coalesc-es with the fin of batter from the other side, whereby the eight cooked cones are joined together. After the die section is raised into the position shown in Fig. 2, the batter, that lia-s run over the sides of the molds when closed, may be removed with a knife, and then the members Q1 may be moved outwardly to the positions shown in F ig. 3 leaving the cooked cones resting upon the arm 18 so that the eight l cones may be removed asv one, by lifting the same, thus facilitating the handling thereof. The cones may be cut apart or otherwise separated at any time thereafter which is found desirable.

As soon as the baked cones have been removed the members 2() and 2-1 may be moved inwardly into contact with the arm 18 and secured in this position by the hook 29, batter may be inserted, the die section lowered and the mold again moved into the baking position. In this manner a oont-inuous baking process may be maintained.

The intensity of the gas fianie is regu lated so that when an operator works continuously filling the molds and removing the baked cones the cones will have just sufficient time to bake thoroughly in their movement around the post.

YWhen the batter is poured into the mold recesses 2() and Q3 Aand the dies 27 are lowered therein the batter will be crowded out of' the recess and a thin film thereof will be causedv to cover the top of the arm 18 so that when the baking has been completed the cones will all be connected by a thin section of material and when the arms 21 ai'e moved outwardly away from the arm 1S thev baked cones will remain on the arm 1S vand may he easily and quickly lifted and disposed of without breaking them apart.

Tt, will be understood that changes in the foi-in of construction and arrangement of parts of nl v invention may be resorted to within thc scope of the following elam li'hat l claim is:
